1 Claim.

The present invention relates to containers such as used for the retention of garbage or other waste material and is constructed and designed to have a lid or cover thereon which will interlock with the main body of the container by merely rotating the lid. The present invention is a modification upon the form of container shown in my copending application, Serial No. 168,758, filed October 13, 1937. In my former application the interlocking of the lid and container was secured by means of an elliptical lid on a circular body and the provision of interlocking formations on the two elements. The present form of can is made with the body elliptical and the lid circular thereby modifying the basic idea of the former application.

The formation of the elliptical body may be secured by either deforming the can from its cir- 'cular form, as a part of the original shaping operation or by a subsequent pressing operation, or by adding sectional flanges at opposite diametrical points on a round can, which makes the upper edge of the can body elliptical and secures the same general result. Both forms of the invention are shown herein.

Either form of the invention affords an inexpensive and eifective means by which the interlocking of the lid and body are secured. It is obvious that other modifications may be adopted to secure the same principles of construction and operation,

In the drawings in which both types are shown:

Figure 1 is a side elevation with the lid in section of the improved can and interlocking lid having the body of the can in the general form of an ellipse;

Figure 2 is a section on the line 2-2 of Figure 1, showing the lid in locked position in full lines and in unlocked position in dotted lines;

Figure 3 is a fragmentary view showing the position of the interlocking lug when the lid is in unlocked position;

Figure 4 is a View of the second form of can with the added flanges, the lid being shown in section; and

Figure 5 is a section on the line 5-5 of Figure 4.

In the form shown in Figures 1 to 3 the can body is indicated at l and the lid at 2, the latter having the downwardly extending rim 3 in which are formed two oppositely positioned lugs 5 which are designed so as to pass beneath the outwardly extending bead or flange 6 on the upper edge of the can body. The lugs 5 are preferably formed by stamping the metal of the rim, but lugs may be attached to the inner surface of the rim, if

.desired.

The lid is circular but the can body is formed as an ellipse or slightly out of round, as will be seen by an inspection of Figure 2. When the lid and body are in the relative angular position shown in full lines in Figure 2 the lugs pass beneath the flange 6 and interlock the lid and can body so that by rotating the lid locking of the parts is secured, and the lid can be unlocked only by relative rotation of the two elements. In Figure 3 the relative position of the lid and can body is shown when in unlocked position.

The deformation of the'can body from round to elliptical form is sufiicient to give the required difference in axial dimensions across the upper edge of the body to secure the interlocking effect. It will be noted that the distance between the inner faces of the lugs is less than the larger axis of the ellipse, but greater than the lesser axis.

In Figures 4 and 5 the equivalent result is secured by the addition of the two relatively short flange elements [0 to the side of a round can. When in the position shown in these views, the lugs 5 pass beneath these flanges, but when turned or less the lugs are free of the flanges and the lid may be lifted. This method of construction is somewhat more expensive than the preferred form, but the effect of an elliptical can body is secured.

It will be noted in both embodiments of the invention shown, that when the lid is on the can body the interlocking formations on lid and body are in axially spaced apart relation both in the locked and unlocked positions of the lid. This enables the lid to be turned angularly through 360 degrees at all times, which facilitates the removal of the lid when such is intended. The locking devices do, however, prevent the removal of the lid by other than human agencies.

What is claimed is:

A container having a circular lid and a body that is elliptical across its upper edge, said lid being formed with a continuous downwardly extending rim or flange loosely fitting around the body to allow for rotation of the lid on the body, said rim having its lower edge formed with a continuous bead that is locally deformed at diametrically opposite points to provide inwardly projecting lugs, said body being formed with a continuous outturrred bead on its upper margin, the inner extremities of the lugs being at a distance greater than the short axis of the body bead so that the lid may be received on the body and rotated to locking position, the distance between the extremities of the lugs being less than the long axis of the body head so as to underlie the bead, in axially spaced relation thereto, in the locking position of the lid.
